Description

Technical Field

[0001] The utility model relates to the field of packaging, and more specifically, to an environmentally friendly cigar moisturizing bag. Background Art

[0002] Cigars are usually packaged in boxes, which use the closedness of the boxes to keep the cigars intact and moisturized. However, with the changes in seasons and regional temperature and humidity, the packaging boxes cannot completely suppress the moisture exchange process between the environment and the cigarettes, causing the moisture content of the cigars in the box to fluctuate, thus affecting their smoking quality. In order to solve the problem of moisturizing cigars during storage, it is necessary to design a moisturizing bag to maintain the humidity balance in the packaging box and keep the cigars at the optimal moisture content. At the same time, the moisturizing bag needs to use environmentally friendly materials and does not cause pollution to the environment. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides an implementation method of an environmentally friendly cigar moisturizing bag. Consumers can choose a moisturizing bag with a suitable balanced humidity according to the local humidity environment conditions, so as to solve the moisturizing problem faced by cigars.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] An environmentally friendly cigar moisturizing package has an outer layer made of environmentally friendly materials, which has functions such as slow-release moisture, printing, and packaging; the inner layer is an intelligent humidity-regulating hydrogel, which can quickly sense changes in environmental humidity in the packaging box and intelligently control the absorption and release of water molecules, thereby achieving the purpose of maintaining the humidity balance of the cigar microenvironment.

[0006] Specifically, the utility model provides an environmentally friendly cigar moisturizing bag, which is composed of a front paper layer, a front sustained-release layer, a moisturizing layer, a rear sustained-release layer and a rear paper layer to form a sealed structure; the front paper layer and the rear paper layer are the outermost layers, and the moisturizing layer is the central layer, which is located between the front paper layer and the rear paper layer; the front sustained-release layer is located between the front paper layer and the moisturizing layer, and the rear sustained-release layer is located between the moisturizing layer and the rear paper layer; the front sustained-release layer and the rear sustained-release layer are made of a degradable film with water vapor permeability, and the moisturizing layer is made of hydrogel.

[0007] Optionally, the front paper layer and the front sustained-release layer can be integrated or separated through a layered composite process; the rear paper layer and the rear sustained-release layer can be integrated or separated through a layered composite process; the moisturizing layer can be encapsulated between the front paper layer, the front sustained-release layer, the rear sustained-release layer and the rear paper layer through processes such as heat sealing and gluing.

[0008] Optionally, the front paper layer and the rear paper layer can be bonded together by heat sealing or gluing to form a sealed structure, or a piece of paper can be folded to form an envelope, with three sides fixedly connected together and the other side being a movable opening that can be opened or closed, thereby encapsulating the front sustained-release layer, the rear sustained-release layer and the moisturizing layer inside. The front sustained-release layer, the moisturizing layer and the rear sustained-release layer are encapsulated in the sealed structure.

[0009] Optionally, the front paper layer and the rear paper layer may be made of the same base paper or different base papers, preferably the same base paper.

[0010] Optionally, the front sustained-release layer and the rear sustained-release layer may be made of the same degradable film, or may be made of different degradable films, preferably the same degradable film.

[0011] Optionally, the base paper used for the front paper layer and the back paper layer is any one or two of the common papers on the market, such as white cardboard, coated paper, kraft paper, etc. These base papers have water vapor permeability, but compared with the front and back slow-release layers, their water vapor permeability is generally higher. By providing the front and back slow-release layers, the rate of water dissipation in the moisturizing layer is reduced.

[0012] Optionally, the degradable films used in the front sustained-release layer and the rear sustained-release layer are any one or two of existing materials such as polylactic acid (PLA) film, polylactic acid-polybutylene succinate (PLA+PBAT) composite film, polybutylene succinate (PBS) film, polyhydroxyalkanoate (PHA) film, polycaprolactone (PCL) film, cellulose film, etc.

[0013] Optionally, the front sustained-release layer and the rear sustained-release layer can be bonded together by a heat-sealing process or by an adhesive bonding process.

[0014] The front and rear sustained-release layers must have a certain water vapor permeability to release moisture slowly. The water vapor permeability is 200-450g / m 2 .24h, to ensure that the moisture in the moisturizing layer is exchanged slowly and evenly with the external environment. Optionally, the water vapor permeability is 200g / m 2 .24h, 250g / m 2 .24h, 300g / m 2 .24h, 350g / m 2 .24h, 400g / m 2 .24h, 450g / m 2 .24h and other selectable water vapor transmission rates.

[0015] The four sides around the front sustained-release layer and the rear sustained-release layer must be fixed and sealed to form a closed area in the space where the moisturizing layer is located, avoiding the formation of a gap between the front sustained-release layer and the rear sustained-release layer, which would cause rapid water and gas exchange between the moisturizing layer and the outside world, thereby affecting the use effect of the moisturizing layer.

[0016] The front paper layer and the rear paper layer are fixedly connected, wherein one preferred solution is to fix the four edges around to form a closed area inside, and the front sustained-release layer, the rear sustained-release layer and the moisturizing layer inside cannot be taken out; another optional solution is that the front paper layer and the rear paper layer are in the form of an envelope, the three edges of the front paper layer are fixedly connected to the rear paper, and the other edge is not fixedly connected, but serves as a movable opening edge, which can be opened or closed, so as to control the taking out of the front sustained-release layer, the rear sustained-release layer and the moisturizing layer inside.

[0017] The front paper layer and the back paper layer need to have the function of printing so as to explain information such as the product name, production unit, and recommended usage environment.

[0018] The moisturizing layer is made of a material containing hydrogel, and one optional solution is that the moisturizing layer is made of a commercially available moisture-regulating material, for example, a fiber-type moisture-regulating material is a common product on the market;

[0019] Another optional solution is that the moisturizing layer uses a polyacrylamide-based intelligent humidity-regulating hydrogel material.

The polyacrylamide hydrogel is a hydrogel formed by polymerization of monomers under the action of an initiator, a cross-linking agent, and an antibacterial factor. The monomer includes acrylamide; the mass fraction of the moisturizing factor contained in the hydrogel relative to the acrylamide monomer is 20% to 60%; the moisturizing factor is at least one of glycerol, L-serine, sodium alginate, and sodium pyrrolidonecarboxylate; the mass fraction of the hygroscopic factor contained in the hydrogel relative to the acrylamide monomer is 20% to 50%; the hygroscopic factor is lithium chloride (LiCl), calcium chloride (CaCl 2 ), sodium chloride (NaCl), calcium sulfate (CaSO 4 ), potassium chloride (KCl), potassium nitrate (KNO 3 ); the initiator is 2-hydroxy-2-methyl-1-phenyl-1-propanone (photoinitiator 1173), and its dosage is 50-100 μL per 10g of acrylamide monomer; the cross-linking agent is N,N-methylenebisacrylamide (MBA), and its dosage is 5-10 mg per 10g of acrylamide monomer; the antibacterial factor is N,N,N-trimethylglycine (betaine), and its dosage is 30-60 mg per 10g of acrylamide monomer.

[0020] The preferred moisturizing layer of the utility model is made by the following method, and the moisturizing layer material has been produced, used and marketed:

After AM was uniformly dissolved, 3g lithium chloride, 33mg betaine, and 10mg cross-linking agent N,N-methylenebisacrylamide (MBA) were added, and stirred on a magnetic stirrer for 5min.

[0049] The cigar moisturizing bag obtained under this condition can control the humidity in the cigar box to about 75% RH at room temperature.

[0050] Example 3

[0051] The environmentally friendly cigar moisturizing bag is composed of a front paper layer, a front slow-release layer, a moisturizing layer, a rear slow-release layer and a rear paper layer (the paper layer and the slow-release layer are not integrated), the moisturizing layer is placed between the front slow-release layer and the rear slow-release layer, and the left edge, right edge, upper edge and lower edge of the front slow-release layer and the rear slow-release layer are sealed and fixed together by a heat sealer.

[0052] The front paper layer and the back paper layer are made of white cardboard with a thickness of 1mm;

[0053] The front sustained-release layer and the rear sustained-release layer are made of cellulose film with a water vapor permeability of 300g / m 2 .24h, thickness is 40μm.

[0054] The moisturizing layer is made by:

[0055] 10g acrylamide (AM) was added to 15g water to form a mixed solution.

After being cross-linked and cured by ultraviolet light for 45s at room temperature, a moisturizing hydrogel material was obtained.

[0056] The cigar moisturizing bag obtained under this condition can control the humidity in the cigar box to about 70% RH at room temperature.

[0057] The cigar moisturizing bags of Examples 1-3 can maintain the relative humidity in the bag between 60% and 75% for a long time. Example 1 and Example 2 use the same paper layer and sustained-release layer, but because the amount of lithium chloride added to the moisturizing layer of Example 2 is less and the thickness of the prepared hydrogel is relatively large, the ambient humidity in the cigar box can be controlled at about 65% RH and 75% RH, respectively. The paper layer and sustained-release layer used in Example 3 are different from those in Examples 1 and 2, and the amount of lithium chloride added to the moisturizing layer is also different, but the thickness of the moisturizing layer is the same as that in Example 1, so the ambient humidity in the cigar box can be controlled at about 70%.

[0058] Example 4

[0059] The environmentally friendly cigar moisturizing bag consists of a front paper layer, a front slow-release layer, a moisturizing layer, a rear slow-release layer and a rear paper layer. The front paper layer and the front slow-release layer are integrated through a layered composite process, the rear paper layer and the rear slow-release layer are integrated through a layered composite process, the moisturizing layer is placed between the front slow-release layer and the rear slow-release layer, and the left edge, right edge, upper edge and lower edge of the front paper layer, the front slow-release layer, the rear slow-release layer and the rear paper layer are sealed and fixed together by a heat sealer.

[0061] The front sustained-release layer and the rear sustained-release layer are made of commercially available cellulose membranes with a water vapor permeability of 215 g / m 2 .24h, thickness is 50μm.

[0062] The moisturizing layer uses a commercially available cellulose humidity-conditioning sheet with a thickness of 5 mm.

[0063] The cigar moisturizing bag obtained under this condition can control the humidity in the cigar box to about 60% RH at room temperature.

[0064] Example 5

[0065] The hydrogel was prepared by the method described in Example 1 of patent application number CN202111404818.6, and the specific method is as follows:

[0066] Add 15g acrylamide (AM) to 50g water to form a mixed solution. After AM is uniformly dissolved, add 0.005g cross-linking agent N,N-methylenebisacrylamide (MBA) and stir on a magnetic stirrer for 2min. Add 6g glycerol and deoxygenate for 15min. Then add 0.05g coupling agent vinyltrimethoxysilane, 0.04g initiator potassium persulfate (KPS) and 25μL catalyst tetramethylethylenediamine (TMEDA). After stirring for 3min, pour into a mold and place in a 60℃ water bath for 3h to obtain a hydrogel.

[0067] The hydrogel is used to prepare a cigar moisturizing bag. The other processes of this embodiment are the same as those of embodiment 1.
